It won't run faster. I will probably load faster.

Did you make a copy of the dictionary returned by getLocals()?

    savedLocals = getLocals().copy()

Each time you run your program you will have to pass it a fresh
copy of this copy, too:

    interpr.setLocals(savedLocals.copy())

The fresh copy will give the restore effect.

Have fun,
